To all whom, it may concern:

Be it known that we, LELAND S. LAD-EEN BURG and SYLVESTER G. PEARsoN,citizens of the United States, residing at Stockton, in the county ofSan Joaquin, State of California, have invented certain new and usefulImprovements in Engine-Supporting Frames; and we do declare thefollowing to be a clear, full, and exact description of the same, suchas will enable others skilled inthe art to which it appertains to makeand use the same, reference being had to the accompanying drawings, andto the characters of reference marked thereon, which form a part of thisapplication.

This inventionrelates to improvements in engine supporting frames, themain object of the invention being to produce a portable enginesupporting frame adapted to receive engines or motors of all kinds for.the purpose of working upon the same for making repairs or similar work.

A further object of the invention is to produce an underslung framemounted in said portable frame and capable of being revolved around apivotal point in any desired manner in order to enable-any part of -theengine or motor to be reached. Said underslung frame may be made, aswill appear, so that itcan be adjusted to such a nicety with respect tothe weight of the engine or motor that such engine will so hang in theframe as to permit the same to be turned in a complete circle withoutany 'eiiort whatsoever.

A further object of the invention is to produce a simple and inexpensivedevice and yet one which will be exceedingly elective for. the purposesfor which it is designed. v

These objects, we accomplish by means of such structure and relativearrangement of the parts as will fully appear by a perusal of thefollowing specification and claims.

In the drawings similar characters of reference indicate correspondingparts in the several views.

Figure 1 is a side elevation of the complete device. Figr is an endelevation of the same. Fig. 3"is a detached view shown characters ofreference on the drawings, the

mounted on beams 2 which may or may not l be provided, as founddesirable, with supporting rollers or wheels 3. Each of the frames 1 isprovided with a vertical arm 4 for the purpose as will appear.

J ournaled in the upper ends of the frames 1 are pins 5, secured to theends of which are disks 6 provided with a plurality-of holes 7 in theirsides. The engine supporting frame is secured to said disks 6 in thevfollowing manner: The side-.frames 8 ofsaid engine supporting frame areprovided with vertical slots 9 4projecting through which are bolts 10having nuts 11 by means of whi'chbolts and nuts, the said members 8 aresecured to the disks 6. The bolts 10 are slidable through the slots 9,whereby by means of the bolts 10 and nuts 11. The

members 8 are braced together by means of angle iron cross bars 14 whichare rigidly secured to the members 8 in any desired manner.

The lower ends of the members 8 are-pron vided with slotted guides 15 inwhich are 'slidable bolts 16, which bolts 16 project upwardly betweentwo cross beams 17 spaced apart on each side of said `bolts' 16 andadapted to be connected by cross bolts 18. These members 17 as will bereadily seen, are adjustable along the lower edges of the members Sandare adapted to receive the engine or motor, which engine or motor wouldbe connected to said beams by means Vof bolts projected through the lugsof said engine and motor and between said member 17 and be securedthereto by means of nuts mounted on said bolts. Any desired xed positionof the members 17 on the members 8 is obtained by tightening nuts 19 inthe upper end of the 4bolts 16.

In practice the engine or motor would be secured to the members 17 inthe manner set forth and then the members 8 would be ad-` said engine ormotor to be perfectly balanced l on the pivotal points 5 which wouldthen permit such engine or motor to be readily turned in any directionwithout a great deal of efort, whereby all parts of the engine or motorcould be easily reached for any purpose desired. Any xed position oft-he engine or motor could be held by means of pins 2'0 projecting'through the arms 4 and engaging, the holes 7.

While We have shown and described the device as having the adjustablefeatures of the underslung engine frame, still if desired such engineframe without any adjustment I could be pivotally swung on the members landbe used in that manner with the same effect, therebeing means ofcourse of fixing it indesired position in its rotation.

' 'From the foregoing description it will be readily .seen that we have'produced Suche device as substantially fulfils the objects oit' theinvention as set forth herein.

While this s eciic'ation sets forth in detail the present and preferredconstruction of the device, still in practice such deviations fromsuohdetail may be resorted toas do lnot form a departure from the scopeof the claims,

.Having thus described our invention what we claim' as new and usefuland desire lto secure by Letters Patent is 1. A device of the characterdescribed comprising the combination of a supporting traine, a pair ofdisks pivotally mountedy on 'pivotally pivot-ally mounted on said framein spaced relation, bolts disposed in said disks and provided withnuts,-independent frame members provided with slots mounted over saidbolt-s, and supporting beams disposed in said independent frame members,as described.

3. A device of the character described comprising a supporting frame, apair of disks mounted on said frame spaced relation, independent framemembers mounted between said disks and being capable of slidingadjustment thereon, projecting arms on said disks, set screws disposedin said arms and engaging said independent frame members and supportingbeams mounted on said independent frame mem-- bers, as described.

In testimony whereof we afiix .our signa tures in presence of twowitnesses.
